Double Membrane Organelles — NEET Biology
📚 Practice ConceptName two cell-organelles that are double membrane bound. What are the characteristics of these two organelles? State their functions and draw labelled diagrams of both.
Which of the following statements correctly describe the characteristics of mitochondria and chloroplasts? S1: Both organelles are double membrane-bound and divide by fission. S2: The inner mitochondrial membrane is relatively less permeable than the outer membrane. S3: Chlorophyll pigments are present in the stroma of chloroplasts, whereas enzymes for aerobic respiration are in the mitochondrial matrix. S4: Both mitochondria and chloroplasts possess their own DNA, RNA, and 70S ribosomes, making them semi-autonomous. S5: The cristae in mitochondria and thylakoids in chloroplasts both serve to increase the surface area for metabolic reactions.
